hello everybody !

I'm working on a simple MATLAB program & I got stuck with something so I'll appreciate it if anyone can help

how can I write an imaginary value in a MATLAB program as input , for example, impedance Z = 100+10i

I'm pretty sure you can do it exactly as you've just typed.

Also, as long as variables "i" and "j" have not been redefined by your program, then use either:

Z = 100 + 10*i

or

Z = 100 + 10*j

If you're not sure about "i" being redefined you can always do "i = sqrt(-1)" first.
